CORPORATION OF CALIFORNIA ADJUSTER FOR SWING CASEMENTS AND THE LIKEApplication filed February 24, 1927. Serial No. 170,638.

This invention relates to adjusters for swinging easements, transoms orthe like, and it is an object of my invention to provide a device whichmay be attached to a sill or other stationary point adjacent theswinging casement, and which is attachable to the casement itself andpermits of swinging motion of the casement. The rattling and banging ofswinging easements such as shutters or blinds during a wind storm isfamiliar to everyone, and it is an object of my invention to remedy thisby providing a casement adjuster that will permit the easement to beleft completely en without the occupants of the residence eing disturbedby such noises.

Another object of the invention is to provide a device which is strongand durable in its construction and which operates efiiciently, andwhich is well adapted to perform the services required of the same.

With the foregoing and other objects in view which will be made manifestin the following detailed description and specifically pointed out inthe appended claim, reference is had to the accompanying drawings for anillustrative embodiment of the invention, wherein:

Figure 1 is a plan view of my casement adjuster showing the sameattached to the sill of a window and to the easement.

Figure 2 is a side view taken along the lines 2-2 of Figure 1 showingthe easement in closed position.

Figure 3 is a sectional view similar to the showing in Figure 2, showingthe easement completely open, and

Figure 4 is a plan view of one element of my device, which element is inthe form of a plate, and is provided so that my casement adjuster may beattached to easements having different sized jambs.

In the accompanying drawings forming a part of this specification, thereference numeral 1 designates a swinging casement such as a window,which has a bottom frame piece 2, moulding 3 and pane 4. The device isshown as being hinged for swinging movement in a plane perpendicular tothe plane of the pane. The sill of the window is designated at 5, and aslot 5 extends through the sill, and it is this slot that my adjustermay be disposed.

My adjuster comprises in combination an angle bracket deslgnated atv 6,having a vertical flange 7 and a horizontal flan e 8. Both of theseflanges are apertured, and the flange 7 is adapted to receive suitablewoodscrews 9 or nails. Bolted to the flange 8 is the flat structureshown in Figure 4 and designated at 10. This plate 10 is provided withan elongated slot 11, and it is through this slot that the same isbolted to the flange 8. A plurality of apertures 12 are formed in oneend of the plate, and suitable woodscrews 13 serve to bolt the plate tothe sill or jamb on the bottom of the slot. An aperture 14: is formed atthe other end of the plate and a small upstanding lug 15 is pivotedthrough this aperture to the plate. The lug is apertured as at 16 andreceives one end of the actual operative casement adjuster. The casementadjuster consists of a barrel 17 having an open end 18 interiorlythreaded as at 19. A second barrel having its external surface threadedis threadedly mounted within the barrel 17. This second barrelisdesigated at 20, and it similarly is open-ended and threaded as at 21.Threadedly mounted within the barrel 20 is a bolt 22 having an eyelet at23, which eyelet is pivotally attached to a bracket 24 on the casement.The threads on the exterior surface of the barrel 2() and the bolt 22may be similar. may be both right-handed threads or both left-handedthreads, or one right and the other a left-handed thread and they may beof the same or of different pitch. The lug 15 acts as a pivoted journal,and a shank 25 is formed on the barrel 17 and extends through thejournal in the lug 15. A plurality of spacing collars 26 may be insertedon the shank 25 so that a proper adjustment of the adjuster is insured.The shank 25 is provided with a square bore therethrough, adapted toreceive a crank 30 having a square shank thereon.

The operation of my device is as follows. The device may be attached tothe jamb and to the easement at any point whatsoever, providing ofcourse, the points chosen are oper- That is, they ativepoints. However,in actual practice I have found that the most suitable points are 7inches from the stafi mould on the casing,

and an opposing point 7 inches out on the sill. The bracket 6 is mountedat this last mentioned point, and the device is. assembled on the same.The bracket 24 is rigid with the frame 2 and does not permit turning ofthe bolt. When the crank is inserted in the square bore and the shank 25is rotated, the bolt 22 will move outwardly from the barrel 20, pushingahead of it the bracket 24 and the casing. Cessation of rotation of thehandle willinstantly cause the casement to stop. and the threads on thebolt and on the barrel are of such pitch that they can not be operatedas a worm, and considerable backward pressure may be applied to thecasement and the adjustment of parts will remain the same. When the bolthas reached the end ofitspath in the barrel as shown in Figure 3, thehead of the same will abut against the annular flange in the barrel 20,and as the barrel 17 continues to rotate, the barrel 20 will moveoutwardly from the barrel 17 and the casement will move outwardly stillfurther. Reversal of this operation closes the casement.

My device may conveniently be constructed of brass, or in fact, of anysuitable material, and has a width of approximately 7 4; inches, whichis a standard width of jamb. When the jambis not a standard jamb, thedevice may still be'employed by means of the plate 10 above described. Ihave shown an adjustment of this plate in Figure 3. If desired however,the plate maybe omitted and the casement adjustermay be applied directlyto the bracket on the sill. It is to be noted then, that my invention isextremely simple in its operation and operates efliciently. Theconventionaljtype of casement adjuster now on the market consists of twopieces-one a bracket adapted to be mounted on the jamb, and the otherapivoted rod on the casement. This rod has a projection on the end ofthe same, and is adapted ,to be selectively introduced into variousspaced apertures in the bracket. This type of device is widely used in'the commercial world and is familiar to all manufacturers of easementsand to the general public. My device is a decided improvement over thisstyle casement adjuster, as very often when the casement sets after afew months of service, or when the same becomes slightly warped due tothe exposure to the weather, the apertures do not line up with thepivoted rod and a readjustment of these parts is necessary. Also, therods become through the slot so that one will not have to open thewindow to get at the blind.

I wish it to be distinctly understood that I do not desire to limitmyself to the use of my casement adjuster as above shown and described.All manner of swinging doors, transoms and the like may be adjusted bymodifying certain operative parts of the combination set forth above, toadapt themselves to the particular use for which they are designed. Onlyin so far as I point out my invention and particularly claim the same,do I desire to be limited thereby.

It will be understood that various changes in the detail of constructionmay be made without departing from the spirit or scope of the inventionas defined by the appended claim.

I claim:

The combination with a j amb having a slot therethrough and a casement,of a bracket attachable to said jamb beneath said slot, an adjustableplate mounted on said bracket, a lug pivoted to said plate, a barrelmounted for rotation in said lug, said barrel being threaded internally,a second barrel threaded externally with threads receivable in saidfirst mentioned barrel, said second barrel being threaded interiorly, athreaded bolt threadedly mounted in said second mentioned barrel, saidbolt having an eyelet therein and a bracket mounted on said casementadapted to maintain said pin in pivoted relationship with said casement,and means on the end of said first mentioned barrel to rotate the same,whereby said second mentioned barrel and said pin will be outwardlyextended from said first mentioned barrel.

In testimony whereof I have signed my name to this specification.
